Modular forward and rearward seat position adjustment system, with integral vibration isolation system

Abstract

A seat position adjuster with a manipulable control shaft carrying a position locking latch and a spring that biases the latch toward a latched position that locks seat position with the spring being part of a vibration isolator selectively deactivated by an isolator lockout. The shaft is rotatively and axially movable relative to a mounting bracket carrying the shaft that also is attached to one rail of a slide mechanism with the latch being urged by spring into operative engagement with the other rail. Spring is captured in torsion rotatively biasing the latch toward the latched position and is active in tension and/or compression isolating the seat from vibration and lateral/longitudinal accelerations. A control shaft of the lockout is manipulable between a locked position deactivating isolation by preventing axial movement of the position adjuster control shaft relative to bracket and an unlocked position permitting relative axial movement therebetween activating isolation.
